CORPORATION OF MICHIGAN.

GAS-PRODUCER.

Patented Jan. 9, 1906.

Application filed June 26, 1905. Serial No- 267,140.

To (bl Z IU/2/077'2/ it may concern:

Be it known that I, Enron SANDNER, a subject of the German Emperor,residing at Lansing, in the county of Ingham and State of Michigan, haveinvented certain new and use ful Improvements in Suction Gas-Producers,of which the following is a specification, reference being had thereinto the accompanying drawings.

The invention relates to suction gas-pr0 ducers, and more particularlyto that type in which the fuel within the gas-producing chamher issupported directly upon the hearth.

The invention consists in the peculiar construction as hereinafter setforth and particularly in the means employed for supporting the mass offuel while removing the ashes and clinker. V

In the drawings, Figure 1 is a central vertical section through thelower portion of the producer. Fig. 2 is a similar sectional view takenin a plane at right angles to that of Fig. 1, and Fig. 3 is a horizontalsection.

A is the casing, which is provided with the lining B, of fire-brick orother refractory material, and preferably inclined at its lower portionto contract the fuelchamber C.-

D is a hearth beneath the chamber C, and E represents laterallyextending passages through which the air and vapor are drawn to the fuelupon the hearth, these passages eX- tending out through the casing A andbeing normally closed by a door or cover F.

l/Vith a producer of this construction in normal operation the fuelsupported directly on the hearth is in the path of the commingled airand vapor entering through the passages E, and thus combustion anddecomposition will be producd within the center of the mass of fuel,resulting in the production of As the fuel is consumed the ash willaccumulate upon the hearth, as well as a certain amount of clinker, andtherefore it is necessary to remove these from time to time through theash-door F. Inasmuch as the fuel is supported solely by the hearth,whenever there is an accumulation of clinker it is difficult to removethe same without also drawing away some of the unconsumed fuel. Toovercome this difficulty, I have devised a construction of temporarygrate which may be used for supporting the fuel above the hearth duringthe operation of cleaning and removing the clinker, this grate being ofthe following construction: G represents separate grate-bars which areadapted to be inserted one at a time into the mass of fuel above thehearth. For supporting and guiding these bars a slot ted bed-plate H isplaced within the lining B and extends out through the casing A at oneside thereof. This bed is provided with a plurality of parallelguide-slots therein, each adapted to receive one of the bars, and toprevent friction or binding of the bars in the slots they are centrallyenlarged, so as to form separated bearings a 1), respectively, at theinner and outer edges of the bed. WVith this construction whenever it isdesired to clean out the hearth the bars G are successively insertedthrough the slots in the bed II and pressed through the mass of fueluntil their ends abut against the opposite wall of the casing. WVhen allof the bars are inserted, the operator may then remove the clinkerbeneath the bars and resting upon the hearth, after which the bars arewithdrawn and the fuel supported again upon the hearth. After theremoval of the bars the openings through which they are inserted areclosed by a detachable cap I, secured to the bed H. Another advantage ofthe construction is that by removing the bed-plate II, which can beslipped out from the slot in the casing, a sufficient opening is madefor the ready removal of clinker adhering to the walls of thefirechamber above the hearth.

That I claim as my invention is 1. In a gas-producer, the combinationwith a casing containing a fuel-chamber and a hearth upon which the massof fuel is normally supported, of means for temporarily supporting thefuel above the hearth comprising a series of separate grate-bars, andparallel centrally-enlarged guide-bearings through which said bars maybe successively inserted and forced through the mass of fuel.

2. In a gas-producer, the combination with a casing containing afuel-chamber and a hearth upon which the fuel in said chamber isnormally supported, of means for tempora: rily supporting the fuel abovesaid hearth comprising a series of separate grate-bars, and a bed withinsaid casing at one side of the fuel-chamber having centrally-enlargedslots forming parallel guide-bearings through which said bars may besuccessively inserted or removed.

3. In a gas-producer, the combination with a casing containing afuel-chamber and a hearth for normally supporting the fuel Within saidchamber, of the bed H arranged at one side of said casing having theparallel slots therein, the grate-bar G separately insertible throughsaid slots and extending in parallel relation across the fuel-chamberabove the hearth, and the detachable cap I for closing said slotted bedwhen the bars are removed.

4. In a gas-producer, the combination with a casing containing afuel-chamber and a hearth upon which. the mass of fuel is normallysupported, of a grate insertible into said chamber above the hearth toform a temporary support for the fuel, and a centrallyenlarged bearingat the side of the casing through which the grate is inserted forming asupport for the projecting portion of the latter.

5. In a gasproducer the combination with a casing containing afuelchamber and a hearth upon which the mass of fuel is normallysupported, of a removable bed-plate inserted within a slot in one sideof said casing above the hearth for the purpose described.

6. In a gas-producer, the combination with a casing containing afuel-chamber and a hearth for normally supporting the fuel within saidchamber, of a bed-plate inserted within a slot in said casing above thehearth forming a guide-bearing and support for temporary grate-bars,said bed-plate being removable to provide access to the fire-pot fordislodging adhering clinkers.

In testimony whereof I afliX my signature in presence of two witnesses.

ERICH SANDNER.
